Abstract
An injector pen is provided that includes a cartridge housing 2, a dose selector housing 10 and a nut 18 for coupling the two housings 2,10 together. The dose selector housing 10 defines an intermediate axial position, where the nut 18 can be temporarily retained in the dose selector housing 10 to form a sub-assembly suitable for transport to a different location. During final assembly of the injector pen, the cartridge housing 2 securely engages with the nut 18 and displaces the nut 18 from the intermediate axial position to a final axial position.
